Hi all,
For what it is worth, I think I may have narrowed the X-axis drift down to a problem with the Mac OS-X version of Carbide Motion.
I have been battling this X-axis drift, going through a number of failed attempts using different feed rates etc. In one instance I even eyeballed the drift happen while cutting air, after restarting an interrupted cut.
In one case, cutting a raised relief map, I noticed that the accumulated drift during the roughing pass appeared to be zeroed when the finish pass started - resulting in a canyon being cut through all mountains
Here comes the clincher, I was driving the Nomad using Carbide Motion Version 2.0.314, Build Date 2015-04-9 on an Apple Macbook Pro running OS-X Yosemite.
Last weekend I switched to a Windows Computer running Carbide Modion Version 2.0.314, Build Date 2015-04-10. Since then I have already done 3 cuts, none of which has had these X-axis problems. To reconfirm, last night I reverted back to the Macbook, just to see the same problem happen again.
Hence a question, are any of you guys experiencing the X-axis drift using a Windows machine to drive the Nomad? If not, then the culprit may be a bug in the Mac OS-X version of Carbide Motion.
